To al? 1li/710m it may concern.:

Be it known that l. Allrnnn l". Tauern. a citizen ot' the United States7residing atl l'tiverside. in the county of Providence and 6 State ofRhode island. have invented een tain new and useful improvements inCarbon-MonoXide Burners. of which the tollo\\' ing is a specification.

The invention has tor an ohiect to pro- 10 vide a readily attachahledevice for furnace doors. so constructed that air admitted through theordinary draft openings ot such doors will be super-heated and projectedinto the hre-box in such a manner as to cause combustion ot cai-honmonoxide gases. s is Well lnown. in all furnaces ot 'the ordinary type.carbon -inonofride gas is formed with carbon dioxide indicatinglincomplete coinluistion of the fuel and repre senting a loss. lt isalso Well lnioivn that carbon monoxide is an inflammable gas, althoughit will not ignite at ordinary teniperaturcs as readily as Irasesordinarily used for heating and illumination. It will burn,

however, when combustion is supported by maintenance o a propertemperature in the gas to he i 1united and the one to supportcornhustion. lt is an object ot my invention. therefore. to takeadvantage ot lthese facts and provide a simple means for attainingr theends in View ltis an important object ot the invention to enable theprovision ot such apparatus ata low cost, which will be readilyadaptable Without numerous different sizes ot patterns, to variousfurnace doors. llt is a further aim to simplify manufacture ot a deviceof this kind having a housing within ,which there are a number ot plateshaving small toraminations. It is a still further object to provide anovel ineans tor directing air in tortuous paths `through such device inconjunction With the torarninate plates.

Additional objects, advantages and teatures of invention reside in theconstruction, arrangement and combination ot parts, as will beunderstood troni the following; description and accompanying drawings,wherein,

There is illustrated formally, tire-'nox l0', which may be huilt in anyapproved tashion. as followed in ordinary furnaces. ln the front wall ot`the tire-box there is mounted the ordinary door and 'traine i0 and 11.in the present instance a rotary draft shutter 12 being illustratedthereon to regir late the admission ot air 'through openings 13 in thebody of the door. Upon the inner .surface of the door, there is boltedor otherwise secured my super-heater and burner il, which is in aboX-lilre toi-rn, and projects a considerable distance into thetire-hoi; troni the door when the latter is closed, the burner beingtrapezoidal in plan with its converfz'ent portions directed inwardlywhereby it may readily clear the door 'traine in 'the opening andclosing movement of 'the door.

The device comprises a housing part inc-luding a inain casting l5, whichincludes the bottom 1G and side Walls 17, which are convergent towardtheir inner parts. At, the front and also at the inner edges of theseWalls. they are joined at the top hy cross bars 18 which are formed ascontinuations of retaining flanges 19 formed on the side Walls i?.immediately inward of which there arc similar flanges 20 iioiininp`channels atthe iront and rear sides ot the housingr, in which there maybe slidahly received toraininate plates 2l and respectively.lnterinedi'atel)v of the housing additional tlangcs 20 are provided ateach side in which a similar torarninate plate 23 is mounted. theperfor-ations in which, however, are in staggered relation toperforations in the first plates. lt, is also to be noted that there areno openings in the intermediate plate immediately adjacent the upper andlower edges of the plate. The top of the housing is closed afterinsertion ot the plates 2i, 22 and 23 by ineans ot a top plate Q4.iitting snugly between the hars 18 and suitably projected upper edges 25of the side Walls 17. lpon the; rear or inner sides of the plates 2l and23. there are secured vertically ein llt) y tended channel pieces 26,each having an open side, which is presented against the respectiveplate upon which it is mounted. Each channel member abuts against thebottom 16 and top plate 24 of the housing, and at the extremities hasopenings or ports 27 formed therethrough opposite the plates to whichthey are secured. The edges of the mutually adjacent channel members arespaced from each other as much as found desirable leaving some openingsin the plates 21-23 uncovered, as may be seen in Fig. 4. They aresecured upon the respective plates b means of bolts 28, engaged throughsuitable apertures in the plates and channel members, and held by nuts29.

For attachment of the device to ai door, central mounting ears 30 areremovably secured to the top and bottom of the housing, as by screwbolts and nuts as shown in Fig. 5. The ears 30 are apertured to receiveordinary stove bolts and may be engaged with the ldoor in a familiarway.

In the event that it is desired to mount the device upon a door havingan inner flat surface, the housing may be presented di rectlythereagainst in the form described, and secured as indicated. In theevent, how` ever, that the door has a curved surface, upon the innerside, an adapter device 3l is iirst secured to the front of the housing,one form of the adapter being shown in Fig. 6, It has an inner flatsi-de adapted to fit snugly against the front side of the hous` ing,being in a shape similar of outline to that of the front of the.housing. It is provided with ears 32 at the ends which may be secured bythe screws 33 holding the top plate 24 in place at each end. The frontside is of a. shape to lit snugly to the door, and provided with ears 30suitably located to enable its mounting upon the door as desired. i

It will be readily understood from the foregoing that a simple applianceis provided, adapted to be manufactured at low cost, which is free fromcomplications, requiring no special adjustment, and is liable in aminimum degree to damage. It is also a very simple matter to put thedevice in place.

In the operation of the device, when properly secured upon a door andthe door is closed, all of the exterior walls thereof will be heated bythe hot gases and tire-shine of the Firebox. Air passing through theforward plate will be largely directed upwardly and downwardly by thechannel members 26, and against the heated top and bottom walls of thehousing. The movement of such air from the ports 27 will then be largelyaway from the top and bottom, in order to pass through the intermediateopenings of the plate 23, the channel members of which will againdeflect the air upwardly and downwardly against the hot top and bottomof the housing before it passes through the final very hot plate 2'2.The movement of the air caused by the channel members will alsofrictionally act upon that air which passes directly through the plates2l and 23 without the channel members, so that a thorough mixture of thehighly heated air coming in contact with the walls of the housing withthat air passing through the intermediate parts of the plate-s will beattained. Passage through the plate 22 will finally heat the air to suchan extent that when coming into contact with the already heated carbonmonoxide in the furnace the gases are nascent or in a ready conditionfor combination. The plates 21 and 23 and the channel members will alsoserve to heat air passing therethrough because of conduction of heatfrom the housing to the plates.

Vhat is claimed A device of the character described coinprising a casthousing having an opening extended therethrough from front to rear, andhaving transverse guide elements at intervals thereon, being constructedfor, and having vertical laniform foraminate plates slidably inserted)in said guides through one side of the housing so as to extend acrossthe opening through said housing,. certain of said plates havingchannelled members mounted at one side and open adjacent the plates, andhaving openings in the sides opposite the plates upon which they aremount` ed, disposed to cause air admitted through the plates to pass ina tortuous manner from one to another.

In testimony whereof I have affixed my signature in presence of twowitnesses.
